Katy Perry reached more than 100 kilometers of altitude during a Blue Origin mission, which made it part of the first crew integrated only by women who crossed the karm line, the limit that marks the beginning of the space according to international standards.
During the flight, The artist lived four minutes of anxiety, which, although it was brief, could have physical and biological repercussions.
While floating in zero gravity, the iconic song ‘What a Wonderful World’ was heard to sing, in the midst of an environment in which the crew unbeclared the belts to experience the ungravation.
Upon returning to the mainland, Perry expressed his deep enthusiasm and emotions by declaring that he felt “Superconnected with life”, In addition to describing his experience as a “surrender to the unknown.” As a symbolic gesture, he kissed the ground when he descended.
How do you affect health travel to space?
– Changes in the cardiovascular system
During the launch, the occupants of the space vehicle face a force between 3 and 6 g, which means feeling that the body weighs several times more than usual.
This intense pressure makes it difficult to breathe, oppress the thorax and temporarily reduce blood flow to the brain. The heart is forced to redouble efforts to pump blood in these conditions, What in people without training can lead to blurred vision or even fainting. Although this episode is brief, its requirement resembles that facing military pilots in extreme maneuvers.

– Immediate effects on the body
Once the microgravity is reached, the liquids that normally concentrate at the bottom of the body move towards the torso and head.
As a consequence, many passengers have a swollen facial appearance, nasal congestion and even alterations in the sense of taste.
Besides, The internal ear system, responsible for balance, conflicts what the eyes perceive, which generates disorientation and nausea in the first moments of the flight. In trips as short as Perry’s, it is possible that the symptoms do not manifest in its entirety, but the body begins to react almost immediately.

– Changes at the cellular level
According to studies carried out by NASA, even brief exhibitions to the spatial environment are sufficient to cause genetic alterations in blood cells.
Modifications were observed in the structure of red blood cells and an activation of defense mechanisms related to oxidative stress.
Research in suborbital flights reveal that these cellular responses can begin in a few minutes and tend to be reversed once it returns to Earth. Even so, The body retains a kind of “memory” of the extreme environment it has experienced.
– Radiation exposure
Although the dose is limited, passengers traveling beyond the earth’s atmosphere, even for few minutes, are exposed to cosmic radiation.
Although it is a reduced amount compared to orbital trips, any incursion beyond the natural shield that represents the atmosphere implies receiving a load of high -energy particles, something that could have cumulative effects if repeated frequently.
